ABSTRACTPurpose: Trachoma surveillance is most commonly performed by direct observation, usually by non-ophthalmologists using the World Health Organization (WHO) simplified grading system. However, conjunctival photographs may offer several benefits over direct clinical observation, including the potential for greater inter-rater agreement. This study assesses whether inter-rater agreement of trachoma grading differs when trained graders review conjunctival photographs compared to when they perform conjunctival examinations in the field.Methods: Three trained trachoma graders each performed an independent examination of the everted right tarsal conjunctiva of 269 children aged 0–9 years, and then reviewed photographs of these same conjunctivae in a random order. For each eye, the grader documented the presence or absence of follicular trachoma (TF) and intense trachomatous inflammation (TI) according to the WHO simplified grading system.Results: Inter-rater agreement for the grade of TF was significantly higher in the field (kappa coefficient, κ, 0.73, 95% confidence interval, CI 0.67–0.80) than by photographic review (κ?=?0.55, 95% CI 0.49–0.63; difference in κ between field grading and photo grading 0.18, 95% CI 0.09–0.26). When field and photographic grades were each assessed as the consensus grade from the three graders, agreement between in-field and photographic graders was high for TF (κ?=?0.75, 95% CI 0.68–0.84).Conclusions: In an area with hyperendemic trachoma, inter-rater agreement was lower for photographic assessment of trachoma than for in-field assessment. However, the trachoma grade reached by a consensus of photographic graders agreed well with the grade given by a consensus of in-field graders. 相似文献

Little is known about how beliefs about heredity as a cause of health conditions might influence preventive and interpersonal behaviors among those individuals with low genetic and health literacy. We explored causal beliefs about podoconiosis, a neglected tropical disease (NTD) endemic in Ethiopia. Podoconiosis clusters in families but can be prevented if individuals at genetically high risk wear shoes consistently. Adults (N = 242) from four rural Ethiopian communities participated in qualitative assessments of beliefs about the causes of podoconiosis. Heredity was commonly mentioned, with heredity being perceived as (1) the sole cause of podoconiosis, (2) not a causal factor, or (3) one of multiple causes. These beliefs influenced the perceived controllability of podoconiosis and in turn, whether individuals endorsed preventive and interpersonal stigmatizing behaviors. Culturally informed education programs that increase the perceived controllability of stigmatized hereditary health conditions like podoconiosis have promise for increasing preventive behaviors and reducing interpersonal stigma. 相似文献

Smart textiles have attracted huge attention due to their potential applications for ease of life. Recently, smart textiles have been produced by means of incorporation of electronic components onto/into conductive metallic yarns. The development, characterizations, and electro-mechanical testing of surface mounted electronic device (SMD) integrated E-yarns is still limited. There is a vulnerability to short circuits as non-filament conductive yarns have protruding fibers. It is important to determine the best construction method and study the factors that influence the textile properties of the base yarn. This paper investigated the effects of different external factors, namely, strain, solder pad size, temperature, abrasion, and washing on the electrical resistance of SMD integrated silver-coated Vectran (SCV) yarn. For this, a Vectran E-yarn was fabricated by integrating the SMD resistor into a SCV yarn by applying a vapor phase reflow soldering method. The results showed that the conductive gauge length, strain, overlap solder pad size, temperature, abrasion, and washing had a significant effect on the electrical resistance property of the SCV E-yarn. In addition, based on the experiment, the E-yarn made from SCV conductive thread and 68 Ω SMD resistor had the maximum electrical resistance and power of 72.16 Ω and 0.29 W per 0.31 m length. Therefore, the structure of this E-yarn is also expected to bring great benefits to manufacturing wearable conductive tracks and sensors. 相似文献

Chlamydia trachomatis is one of the most common causes of sexually transmitted diseases in sexually active males and females. Infertility is one of the serious complications of urogenital chlamydial infections. This study was carried out in Chuwahit town and the surrounding village, which is located southwest of Gondar town. The main objective was to estimate the prevalence of urogenital Chlamydia trachomatis among males aged fifteen years and above. The design used was a cross sectional survey. First catch urine was collected from males 15 years and above and interviews were made using a questionnaire. The urine samples were tested with an Enzyme Immuno-Assay (EIA), which is useful in rapid detection of chlamydia antigen. Among 199 males included in the study, thirty-three (16.6%) had laboratory evidence of urogenital Chlamydia trachomatis. The mean (SD) age of the study subjects was 29.3 (+/- 9) years. Students (8 out of 21, 38%) had the highest prevalence of urogenital Chlamydia compared to the other groups (OR = 4.10, 95% CI = 1.12, 14.48). The magnitude of urogenital chlamydia infection in males was high in the study area. Health professionals need to consider genital Chlamydial infections in the management and control of sexually transmitted diseases. Increasing the awareness of students towards urogenital Chlamydial trachomatis and teaching them about the benefits of using condoms is recommended. 相似文献
